5 Claims.

my invention constitutes an improvement upon the auxiliary hoods orguiding shields for the steam plumes discharged from such Vaporizers, a

prior type of such hood being. shown in my prior joint patent with N.Lawner,'l lo. 2,123,509, dated July'12, 1938 for Electric Vaporizers.

An object of the present invention is to improve the hood so that agreater concentration of steam This is accomplished by constructing thehood so as to completely enclose the st-arn plume instead-of shieldingit only at the top as in the prior invention. In addition to securin ashield which completely encloses the plume, I also so designthe same sothat it may be folded against the main container so that the whole maybe packed readily for shipping or storing in-ralmost as small a space asthe prior simple type of shield. In one form of my invention, it may beso'folded as to form an extra long shield for special uses.

Referring to the drawings, in which several forms of my invention areshown,

Fig. l is a side elevation of my improved complete shield with the partsfolded in a position for shipment or storage;

Fig. 2 is a view of the same;

Fig. 3 is a side elevation of the same showing the hood in use andenclosing-the steam plume, and also showing by dotted lines severaldifferent positions the parts may assume;

Fig. 4 shows a further shape'the shields may assume if th patient islocated-ate. distancefro-m the Vaporizer;

Fig. 5 is a vertical section of a modified form of shield in which theshield is conical shape and fits directly on the spout of the vaporizer;

Fig. 6 is a perspective view of the form of shield shown in Fig. 5;

Fig. 7 is a side elevation of a still further form of the invention inwhich the shield is in the form of a split hollow cylinder as in Fig. 1,but is detachably mounted on the spout as in Fig. 5.

The vaporizer itself be of any suitable form, being shown as comprisinga glass jar I having a detachable top 2 to which is secured the heatingelectrodes 3, which project downwardly into the water in the jar andthrough which electrodes electric current is supplied by means of theprongs or terminals 4: projecting above the top. On the top is also aconical spout 5 or nozzle through which the steam is discharged. Thedevice be used either with or without added mediate its ends. shown infull lines in Fig. 3,'the upper and lower medicine which-maybeplaced-either in the container I or in a separate container, not shown,as more fully described in my prior Patent No. 2,123,509 for ElectricVaporizer.

The jar isshown as normally held in an open- Work sheet metal stand 6,having'a base I, one or more uprights 8 and a top spring ring 9 open atthe front'to receiveithe jar.

My improved shield-is madein' two or more complementary parts'which whenin place form a funnel for the ,guidancerof the steam plume. As

shown the parts arelin the form of upper. and

ring 9 through a plurality'cf pivoted links I2, l3,

l2, 13, connected to points fill-located near the rear end of thisshield. Thepivot points being 'su'fliciently tight'to hold-the shieldsin adjusted position, but nottoo tightto' interfere with readyadjustment. The bottom half is hinged at each side to the top half atintermediate points 5! through other links I l, ld', hinged-to thebottom shield'at points 52 near thefront thereof. All

"pivots also being sufficiently 'tight to hold the shields in theadjusted position.

Links M and Mare pivoted to the upper shield'at points inter- In oneoperating position, as

shields form a hollow generally cylindrical shield around the steamplume with the upper edge of the lower half fitting within the loweredge of the upper half. The points of attachment or hinges '5l of thelinks lltothe lower shield enter slots or cut-outportio'ns l5 on'eachside which'are formed for this purpose in each under edge of the uppershield. If a cone-shaped shield is desired the tapered parts of theshields adjacent the steam spout are pressed partially together, asshown by dotted lines in Fig. 3, thus spreading the open ends.

If a longer shield is desired, the two parts may be folded as shown inFig. 6, in which case both shields lie above the steam plume, but thelower half extends beyond the upper half so as to give a shield ofalmost twice the length obtained when the shield is folded as shown inFig. 3. In this case also, the pivot points 5| connecting the normallylower shield to the links I4, lie within the cut-out portions I 5.

For shipment and also for storage the two shields are readily folded asshown in Fig. 1. To accomplish this purpose, the lower shield may befirst folded within the upper shield with the tapered end II which facesinwardly in Fig. 3

and opposed tapered end l of shield l 0 reversed so as to lie adjacentthe squared end 20 of the upper shield. The two shields are then rotateddownwardly on the links l2, [3 to clear spout 5 so that the shieldsinterfit and partially enclose the vaporizer in the front. This forms avery compact arrangement which may be packed in almost as small a spaceas that occupied by the half shield device of the prior art.

Figs. 5 and 6 show a very simple form of the invention in which agenerally conical shaped shield is employed. In this case also, theshield is made of two parts 39 and 3|. The parts in this case beingseparable so that they may be taken apart, removed from the vaporizerand folded against the same for shipment, as shown in dotted lines inFig. 5. One of the halves of the shield is fitted with a metal attachingmember 32 having a conical shaped opening 33 to fit over the steam spout5 and to hold the part in place when in use. The two halves are providedwith inter-fitting edges 34 and 35 so that one half may be readilydetached from the other by sliding or bending.

Still a third form of the invention is shown in Fig. '7. In this formthe shields when in use are in the shape of a cylinder 35. The cylinderis again split into two parts 36 and 37 so that it may be separated andfolded against the container for shipment and storage. In this case oneend of one of the halves is provided with a cross bar 38 to which themember 32 containing the conical hole 33' is secured for mounting on thesteam spout as in Fig. 5.

From the foregoing, the operation of m invention and its utility will bereadily apparent.

Since many changes could be made in the above construction and manywidely different embodiments could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription and shown in the accompanying drawings shall be interpretedas illustrative and not in a limiting sense.

What is claimed is:

1. A two part steam directing means for vaporizers comprising a pair ofhollow, complementary half-cylinders, a double link hinging one partadjacent one end to the vaporizer and a link hinging the other partadjacent one end to the first part at an intermediate point in suchmanner that the two parts may be folded to form complementaiy guides forthe steam plume or alternatively folded one Within the other to lieagainst the vaporizer for shipment.

2. A steam directing metallic shield for vaporizers, comprising a curvedsemi-cylindrical half shield pivoted to the vaporizer, a complementaryhalf shield, a link pivoting the latter to said first half at a pointadjacent the near end of the latter and at an intermediate point on thefirst half, whereby the second half may form either a cylindrical guidecomplementary to the first half or be folded forwardly upside down toform an extension of the first half shield.

3. A two part steam directing means for vaporizers, comprising a pair ofhollow half-cylinders, a pair of hinged links on each side of one partfor hinging it to the top of the vaporizer, a link on each side of thecylinders hinging them together, said link being pivoted near the middleof the first-mentioned part and near one end of the second-mentionedpart, whereby the two parts may be folded to form complementary guidesfor the steam plume or to form an extended upper guide for said plume,or folded one within the other to lie against the vaporizer forshipment.

4. A steam directing means for vaporizers, comprising a first or uppercurved shield, a pair of links at each side thereof pivoting it to thevaporizer, with its concave side normally facing downwardly, a second orlower complementary shield, a link at each side thereof adjacent thenear end, and attached to the first shield near its middle with itsconcave side normally facing upwardly, whereby the second shield mayform either a lower guide complementary to the first shield oralternatively folded within the first shield and both shields foldedagainst the side of the vaporizer.

5. A steam directing means for Vaporizers as claimed in claim 2, whereinthe first half has a cut-out portion within which the pivot connectingthe second half to its link lies when the two halves are folded to forman extended shield.
